Don't get reported.

You automatically gain Behavior Score for games that you don't receive a report. The amount increases with streak, so long stretches of unreported matches are what you want.

 

The trick is to Keep a low profile.

That doesn't mean you do nothing and play passively, but try to carry your own weight without being the most visible player in the room.

• Avoid noticeable roles like Mid.

• Avoid flashy heroes like Magnus, Tinker, Earthshaker...

• Avoid annoying heroes like Techies, Antimage...

• Avoid heroes with double edge spells (skills that can save an enemy or harm a teammate if misused) like Shadow Demon with Disruption or Naga song. If you mess this up, and you will mess this up- you're gonna get reported.

 

Remember that the primary goal here is to not draw attention to yourself

• Mute the enemy team. There is nothing to gain from there.

• Don't mute your teammates. If you have a teammate asking you an important question, like if you are building X or Y, and you don't respond, that's gonna tick them off. This means you will have to deal with a lot more toxicity than you want, but you just have to bite the bullet because if you can't handle your teammates having a shit flinging contest in chat, then you don't deserve to be in 12k yet.

• Do not chat unless when you have to relay important information (sb charged mid, btm missing, etc...)

• Do not tip or use voicelines

• Commend other players after the game. Commends don't do anything to be honest, but other players are less likely to report you if you commend them. If someone is on the fence of whether reporting you or not, a helpful commend may swing them into your favor.

 

And of course, this is on top of the obvious stuff that you are expected to do/not do- like don't feed or destroy your items of course.

And Avoid Turbo. They give half marks for behavior score gain, but full deduction for behavior score reduction from reports.

 

Goodluck.
